Last November, Coloradans voted to approve a constitutional amendment on recreational marijuana. The measure, Amendment 64, will allow Colorado adults–21 and older–to purchase up to one ounce of marijuana for recreational use from specialty marijuana dispensaries (which could open as soon as January) and to grow up to six marijuana plants–with only three flowering at a given time–in their homes.

Video surveillance of pot growing will become established by an agency that will oversee seed-to-sale tracking next year.

The measure also limits possession up to an ounce for personal use. And selling marijuana without a license, purchasing marijuana from a party who is not licensed as well as public use of marijuana will remain illegal.

For the first few months, Colorado’s marijuana industry be restricted to individuals and shops licensed to sell or produce medical marijuana. Licenses will be granted only to residents of two years, and investors will also need to meet the residency requirements.
